Description

Disk array

Technical field

The utility model relates to technical field of memory, is specifically related to a kind of disk array.

Background technology

Disk array is a memory device less by a plurality of capacity, that the higher entity disk combination of stability forms.In technical field of memory, disk array is just obtaining increasingly extensive use.

In the prior art, being applied in the entity hard disk in the disk array, is a kind of mechanical type hard disk.This hard disk mainly is made up of magnetic disk sheet and several magnetic heads of one or several circles, and the rotation of disk sheet needs diskette motor to drive, and the mobile seek motor that needs of magnetic head drives.In at random data access process once, hard disk at first will drive on the magnetic track that magnetic head moves to the data place, waits for that then the disk sheet rotation delivers to this track data the position of magnetic head.This structure causes this hard disk that certain restriction and bottleneck are arranged on access speed.In order to promote the access speed of hard disk, just must carry out motor and quicken, cause disk array to exist energy consumption than problem big and high heat.

Therefore, in order to guarantee the operate as normal of disk array, must consider the heat dissipation problem of disk array.In the prior art, disk array is all realized heat radiation by fan assembly.This radiating mode not only brings the big problem of noise to disk array, and when this fan system breaks down, may cause the disk array job insecurity, even disk array is quit work and causes losing of significant data.Simultaneously, this radiating mode need be provided with the additional space support for fan assembly, has reduced taking up room of disk, has reduced the number of disks that can arrange in the unit space.In addition, this radiating mode need be provided with extra power support for fan assembly, has further increased the energy consumption of disk array.

In sum, disk array of the prior art exists that energy consumption is big, noise is big, the less problem of stability number of disks lower, that unit space can be arranged.

The utility model content

The utility model embodiment provides the hard disk that a kind of energy consumption is less, noise is little, stability is higher, unit space can be arranged a fairly large number of disk array.

A kind of disk array that the utility model embodiment provides comprises: power module, cascade module, Backplane Plug Frame and some hard disks; Described power module, described cascade module and described hard disk are arranged in the described Backplane Plug Frame; Described power module is connected with described cascade module; Described hard disk is a solid state hard disc, and described cascade module is connected with described solid state hard disc.

Among the utility model embodiment, hard disk adopts solid state hard disc, because the mechanical type hard disk that disk array adopts in the relative prior art of solid state hard disc, has the characteristic that energy consumption is low, heating is little, and disk array is combined by some hard disks, so present embodiment disk array of the prior art relatively has the advantage that energy consumption is low, heating is little.It is little to generate heat during again because of present embodiment work running, can not need to be provided with fan assembly and dispel the heat, so can avoid the problem that noise is big, stability is lower that fan assembly brings in the prior art, makes present embodiment have little, the stable advantage of higher of noise.Present embodiment can utilize the shared space of fan assembly in the prior art simultaneously, improve the hard disk quantity that unit space can be arranged, so the relative prior art of present embodiment also has the bigger advantage of memory capacity.
